A convenient environment to write LaTex

More than one year ago, I wrote a paper about how to accelerate Deep Learning training for sparse features and dense features (images). For writing this paper, I installed a bunch of tools and plugins in my Mac-book and fixed a lot of errors for them by searching Google. Seems preparing LaTex environment on a local computer is really a pain in the neck.
Fortunately I found a convenient way today.
First, download your favourite template. For me the best template is CVPR-2020, from which anyone could download template. The template is a zip file.
Second, go to overleaf.com, sign up a new account. Then, in the top-left of the page, click “New Project”, and click “Upload Project”, choose the zip file above.
Third, now you would see a beautiful IDE for writing LaTex.
